CLOSURE GAP.

Application led May 14, 1924. Serial No. 713,203.

To all who/m it may concern.

Be it known that I, EDWARD J. KINGWILL, a citizen of the United States, residing at Santa Monica, in the county of Los Angeles and State of California, have invented new and useful Improvements in Closure Caps, of which the following is a specification.

This invention relates to closure caps for containers and the closure cap of my invention is particularly suited for collapsible tubes holding a pasty substance, such, for example, as tooth paste and shaving paste.

An object of this invention is the provision of a closure cap pivoted on a container and comprising means for locking the cap on the container when the latter is closed by the former.

Another objectA of this invention is the provision of a cap comprising means for olding the cap in thrown-back position, when the container, to which the cap is pivoted, is in inverted. position.

With the foregoing objects in View, together with such other objects and advantages as may subsequently appear, this invention consists in the construction and arrangement of parts hereinafter described and claimed and illustrated -in the accompanying drawings, in which:

Figure 1 is a side elevation of a container showing the improved closure cap of my inventiony attached thereto,

Fig. 2 is a plan view of Fig. 1,

Fior. 3 is a section taken on the line 3-3 of Fig. 1,

Fig. 4 is a view similar to Fig. 1, but showing the cap in thrown-back position,

Fig. 5 is a plan view of Fig. 4, and

Fig. 6 is a view similar to Fig. 2, showing a spring clip disengaged from a projection on the container.

Referring to the drawings for a more detailed description thereof, the numeral 7 indicates a collapsible metallic tube of the type well known as containers for pasty material, such as tooth paste. The top of the tube 7 has a plain tapered nipple 8 frming the orifice of the tube. A cap 9 is adapted to lit closely over and around the nipple Y8, having a tapered inner periphery for that purpose.

A groove is lcut on opposite sides of the cap 9 and into these grooves are fitted portions of a single piece of spring wire 10 formed into a forward loop 11 and a rear loop 12. The rear loop 12 has a rear end portion 13 which is pivotally mounted in a bearing 14 formed integral with the top of the tube 7. The sides of the rear loop 12 adjacent the bearing portion 13 closely it the ends of the bearing 14. Notches 15 are cut in the ends of the bearing 14 adjacent the bearing surface of the bearing 15 and these notches are provided for the purpose of engaging'the sides of the loop 12 when the cap is in thrown-back position, as shown in Figs. 4' and 5; when the sides of the loop.

12 are thus engaged by the notches 15, the cap is prevented from closing the orifice of the tube when the latter is in inverted position.

A projection 16 comprising a head 17 and a neck 18 of smaller cross section than the head is formed on the top of the container 7 and is adapted to' engage the forward loop 11 of the spring wire 10. The internal diameter 2() designated in Fig. 5 of the loop 11 is smaller than the corresponding diameter of the head 17 of the` projection 16, but being made of spring wire, the loop 11 may be passed over the head 17 to engage the neck 18 by pressing inwardly on the extensions 11a formed on the end of the loop, and will be held in engagement with the neck until released by inward pressure exerted on the extensions 11al and subsequently exerting an upward pressure on said extenslons. The position assumed by the loop 11 when inward pressure is exerted on the extensions 11a, is illustrated in Fig. 6.

Thus, it will be seen that I have provided in a container, a cap, a single fpiece of spring wire secured to the cap and pivoted to the container, a projection on the container, said projection comprising a neck and a head, said wire being formed into a resilient loop adapted to be passed over the head of said projection and t0 engage the neck of the same to hold said cap in closing position.

This invention has been described, but modifications thereof may be devised without departing from the spirit thereof, and it is to be understood that such modifications come within the scope of this invention.

What is claimed is:

1. In a container, a cap, a single piece of spring wire secured to said cap and pivoted to the container and a projection on the container, said wire being formed into a resilient loop adapted to engage said projection to hold said cap in closing position.

2. In a container, a cap, a single piece of spring Wire secured to the cap and pivoted to the container, a projection on the container, said projection comprising a neck and a head, said Wire ,being formed into a resilientloop adapted to be passed over the head of said projection and to engage the neck of the same to hold said cap in closing position. y

3. In a container having a cap, an eye forming a pivotal bearing `for a single piece ofxwire, a projection having a head also 'at- 15 v tached to the container, a single piece of Wire passing through the bearing having straight portions passing through lthe cap,. lapped portions of the wire beyond the cap forming a resilient loop to engage thel pro- 20 jection, and linger grip extensions on the ends of the Wire.

In testimony whereof I have signed my name to this specification.

EDWARD J. KIN GWILL.
